Electro-deposition of superconductor oxide films

A method for making a superconducting oxide precursor film, said method comprising:

• a) providing an electrodeposition bath comprising an electrolyte medium and a substrate electrode;
• b) forming an electrolyte solution by providing to the bath soluble metal salts of a plurality of respective metals, oxides of which metals are capable of exhibiting superconductor properties;
• c) electrodepositing ions of each of the respective metals onto the substrate electrode while bubbling oxygen into said electrodeposition bath to form a first electrodeposited superconducting oxide precursor layer thereon comprising a mixture of the respective metals and oxides of the respective metals in proportions that are sufficient to form a superconducting oxide film should the respective metals in the first electrodeposited layer be subsequently further oxidized;
• d) removing said substrate electrode having said first electrodeposited layer thereon from said electrolyte solution;
• e) depositing a layer of silver onto said first electrodeposited layer;
• f) immersing said substrate electrode having said first electrodeposited layer deposited thereon and having said silver layer deposited on said first electrodeposited layer into said electrodeposition bath;
• and
• g) electrodepositing ions of each of the respective metals onto the silver layer while bubbling oxygen into said deposition bath to form a second electrodeposited superconducting oxide precursor layer thereon comprising a mixture of the respective metals and oxides of the respective metals in proportions that are sufficient to form a superconducting oxide film should the respective metals in the second electrodeposited layer be subsequently further oxidized.
